Liquid Natural Gas barge supplies power to German cruise ship in technology breakthrough

HAMBURG, Germany – For the first time in the history of passenger shipping a cruise ship has received environmentally friendly power from an LNG hybrid barge.
The breakthrough came as Becker Marine Systems’ barge, Hummel, provided 7.5 megawatts of low-emission power to the cruise ship AIDAsol during her layover in Hamburg on Saturday.
“With this successful premiere, the Port of Hamburg is serving as a global role model,” Henning Kuhlmann, a managing director of Becker Marine Systems, told the media.
“Credit is also due to our partner AIDA Cruises, who were deeply involved in this technically challenging project,” Kuhlmann added. Up until now, only a few other ships have been able to receive power from such a barge, but they have always been specialised commercial vessels. “Nevertheless, to improve air quality at port cities preferably all modern seagoing vessels should be able to do this in future,” insists Kuhlmann.

The 76.7m long and 11.4m wide barge has been developed by the Hamburg-based company and works like a floating power plant generating power via a gas container filled with 15 tons of liquefied natural gas (LNG). In the gas processing plant, the cryogenic liquid is heated and then passed on to five gas Caterpillar motors on the barge, which then produce electricity.

Compared to conventional marine diesel powering diesel electric engines, with 0.1 percent sulfur content, the barge emits no sulfur dioxides or soot whatsoever. Emissions of carbon dioxide and nitrogen oxides are also significantly reduced and it is therefore deemed the cleanest option for providing shoreside electrical power to cruise ships, says Kuhlmann. Becker Marine Systems is planning to extend operations by offering the environmentally friendly LNG technology to container ships, bulkers and tankers as well in the future in the port.

“With this, so far unique worldwide pilot project for the energy supply of cruise ships using LNG during idle periods, we have opened a new, forward-looking chapter on environmental protection in the port of Hamburg,” AIDA President Michael Ungerer said in a release. The first of AIDA’s new generation ships will be homeported in Hamburg in the spring of 2016.

Aidaprima is the first cruise ship in the world to have a dual fuel engine and both a shore power connection and a comprehensive system for exhaust after-treatment. The vessel may, depending on availability, be operated on LNG fuel and a recent study by Hong Kong authorities estimates that only 35 international cruise ships, about 16% of the global fleet, are expected to be equipped to use LNG shore
